RESUMO
OBJECTIVE: To identify disruption due to dizziness symptoms following deployment-related traumatic brain injury (TBI) and factors associated with receiving diagnoses for these symptoms. SETTING: Administrative medical record data from the Department of Veterans Affairs (VA). PARTICIPANTS: Post-9/11 veterans with at least 3 years of VA care who reported at least occasional disruption due to dizziness symptoms on the comprehensive TBI evaluation. DESIGN: A cross-sectional, retrospective, observational study. MAIN MEASURES: International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes of dizziness, vestibular dysfunction, and other postconcussive conditions; neurobehavioral Symptom Inventory. RESULTS: Increased access to or utilization of specialty care at the VA was significant predictors of dizziness and/or vestibular dysfunction diagnoses in the fully adjusted model. Veterans who identified as Black non-Hispanic and those with substance use disorder diagnoses or care were substantially less likely to receive dizziness and vestibular dysfunction diagnoses. CONCLUSIONS: Access to specialty care was the single best predictor of dizziness and vestibular dysfunction diagnoses, underscoring the importance of facilitating referrals to and utilization of specialized, comprehensive clinical facilities or experts for veterans who report disruptive dizziness following deployment-related TBI. There is a clear need for an evidence-based pathway to address disruptive symptoms of dizziness, given the substantial variation in audiovestibular tests utilized by US providers by region and clinical specialty. Further, the dearth of diagnoses among Black veterans and those in more rural areas underscores the potential for enhanced cultural competency among providers, telemedicine, and patient education to bridge existing gaps in the care of dizziness.

Background: The lateral muscle-sparing approach total knee arthroplasty (TKA) has been detailed and indicated selectively for severe valgus deformities. We present the largest, to date, consecutive series of lateral subvastus TKAs and we hypothesize that preoperative alignments would demonstrate no differences in range of motion (ROM), knee society scores (KSS), kneeling ability, patient satisfaction, or complications. Materials and methods: This retrospective study examined 931 primary TKAs in 824 patients performed through the lateral subvastus approach with one to two years follow-up. All primary TKAs performed between July 2020 and February 2022 were included. We used descriptive statistics, chi-squares, and analysis of variance (ANOVA) to examine the cohort. Significance was set to p < .05. Results: Patient's ROM significantly improved by six weeks, (1-117°, P < .05) with continued improvement by one-year, (0-121, P < .05) with no significant differences in alignment in extension, (P = .142) or flexion, (P = .253). There were also no significant differences in alignment in KSS scores at six-weeks, (P = .635), three-months, (P = .829), six-months, (P = .836), one-year, (P = .641) or two-years, (P = .776). There were no significant differences in kneeling ability, (P = .563), and 85% of patients reported being able to kneel. There were no differences in patient satisfaction, (P=.436), and 90% of patients reported being satisfied. There was a low 8% complication rate in this cohort. Neutral and varus knees were less likely than valgus knees to develop deep vein thrombosis (DVT; P < .05) or have a medial collateral ligament (MCL) injury (P < .05). Conclusions: Patients with varus, valgus, and neutral knees had similar outcomes when using a lateral subvastus approach to TKA in ROM and KSS that were stable over two years with similar kneeling ability and satisfaction. There was a low incidence of complications with neutral and varus knees at the lowest risk. A lateral subvastus approach to TKA can be safe and effective for all knee deformities.
